    Where are positive and ground points on the human body.
    Our brain helps with the heat,we know that our body has
    electrons. An E.K.G. machine measures our bodies pulses
    and the machine has a positive and negitive anode
    connection. So what are your opinions or is there a science.

    Oh my goodness.... Did Loosie just ask an...an....electronics question?????

    Hahaha, in all seriousness, though, I've often wondered the same thing. How do they connect terminals to your body to pick up these signals? There must be a relative + and -, I've just never known where they are....

    The signal is picked up from your pulse that you can feal
    in your neck. We have a medic on the Forum.

    well, signal across the heart is a vector. The ECG will look different depending on the arrangement of electrodes but there is a standard "grounding" electrode used to get rid of excess noise - hooked up to right leg. Just starting out myself, so...

    Or maybe it is the left leg?

    my book says right leg driver, tried it out - works with three leads, reduces noise

    What are you trying to figure out? An ekg doesn't use + -. Its just measuring the muscle movements from like 8 points of your body where your blood pumps. Thats why in bed hooked up to the machine if you lean forward or move in any way it starts going BEEP BEEP BEEP BEEP and your wave form jumps 1000 fold. I might be wrong with this but I'v had a lot of EKG's and monitors in the past 6 months and all signs pointed to the sensors measuring muscle movements.
    The tens does have a + - and you can hook it up anywhere on your body to make what ever muscle you want jump, or flex or do what ever you want via electrical signal. If you have a bad back, neck or hurt muscle or ligament its amazing.

    The bodies ground point,find it and have every one agree as fact.
    An opinion will not work.

    Some opinions are more factual than others.

    here is an interesting one - a commercial circuit. Points for electrodes are labelled as ground and reference. First thought that measurements were taken with respect to ground but now reasonably sure that there are two different reference electrodes and ground electrode serves to for common mode rejection. So where is ground? I think whereever you want it to be unless one is touching a metal pipe and a live wire at the same time, then it is pretty clear ...

    Here is something I run across, have no time to read full article...

    kind of old, wonder what the progress is...

    I think that the truth with medical science is likely so complex that we probably won't really know for about another 200-years.
